The outer knob defines a knob lumen extending longitudinally therethrough and longitudinal apertures disposed in radially spaced relation relative to a distal lumen portion of the knob lumen. The intermediate collar is disposed within the knob lumen and defines a collar lumen extending longitudinally therethrough. The inner sleeve is disposed within the knob lumen and extends through the collar lumen. The retaining clip includes a curved body disposed within an annular groove defined in an exterior surface the inner sleeve and prongs disposed at opposed ends of the curved body that are aligned with the longitudinal apertures of the outer knob. The screws extend through the prongs and into the longitudinal apertures to secure the outer knob and the inner sleeve with one another.
